Abstract
Bioactive agents are dosed by a jet dispenser using inkjet technology, such as that used in printing devices. The jet dispenser dispenses precise amounts of bioactive agent into a fluid manifold, in which the bioactive agent can be mixed with an infusion liquid for infusing into a patient. A controller may control delivery of one or more drugs, timing of drug administration, or change drug regimens in response to a changing medical condition of a patient. A drop detector can be used to detect various characteristics of the droplets of the bioactive agent dispensed by the jet dispenser and provide a feedback signal to the controller to determine whether a detected characteristic satisfies a predetermined condition. Methods for administering bioactive agents using a jet dispenser also are disclosed.
